1988·Between Madura and Mundrabilla, Nullarbor Plain, Western Australia

Australia.Knowles family · they say a light lifted their car

On January 20, 1988, at about 4:20 am, Faye Knowles and her three adult sons were driving on the Eyre Highway across the Nullarbor Plain when they said a luminous one-meter object shaped like an egg in a cup pursued them, allegedly lifting and shaking the car, with smoke in the cabin and altered voices. In Ceduna, the police sergeant who examined the car told UPI it was covered in “a thick coating of black ash”; but, according to meteorologist A. T. Brunt, inspections “showed [nothing] unusual” and dust analyses found no anomalous material. In 1989 Brunt explained the light as a truck's headlights distorted by a superior mirage.

Why: The conclusion "that the first impressions of the Knowles family were correct, ie, that it was indeed 'a truck approaching from the east'. It was the distorted image of its headlights which was so frightening and bizarre" (through a superior mirage). (Brunt, A. T., “The 1988 Nullarbor UFO Mystery – Solved”, The Skeptic 3(5), 1989 ↗)

What happened

At about 4:20 a.m. Central Daylight Time on January 20, 1988, Faye Knowles and her three adult sons, Patrick (24), Sean (21) and Wayne (18), were driving east in their Ford Telstar on the Eyre Highway, about 40 km west of the Mundrabilla Roadhouse, deep in the Nullarbor Plain of Western Australia, a remote and almost empty region. According to meteorologist A. T. Brunt, they saw a light over the road ahead; at first they took it for a truck coming from the east, but it grew brighter and bigger and frightened them. The driver said it appeared and disappeared "after jumping about a bit," and described it as "like an egg in an eggcup and about 1 metre wide," "bright and white with a yellow centre." Brunt refers to a male driver, and the report UFO Research Australia wrote six days later and the later accounts put Sean at the wheel; the UPI wire story of January 21, quoting the police, says instead that Mrs. Knowles was driving.

According to all four, the object settled over the car. The family described several physical effects: the car was briefly "lifted" off the road, shaken and dropped hard, and a tire was damaged; black smoke or mist with a strange smell came into the cabin; their voices changed, becoming slower and distorted; and the family dog, traveling with them, panicked. Faye Knowles said she reached out of the window and touched "the hood" (as UPI reports it): "It was soft, warm and spongy." Sean said they were doing about 110 km/h when the object came over them and lifted the car.

A truck driver, Graham Henley, heading east some 10 to 15 km ahead of the Knowles family, said he saw a light "too high up to be another truck or vehicle" that "disappeared and reappeared," and later met the family at Mundrabilla. According to Brunt, of the vehicles within 30 or 40 km, his was the only one whose occupant reported an unusual light. That night the crew of a tuna boat in the Great Australian Bight, hundreds of kilometers away, also saw a vertically elongated light, and the Ceduna sergeant spoke of four reports in all: the family, the trucker, a tuna-spotting plane and a trawler. Henley did not see the "lifting": according to the Skeptoid program, no witness to that episode ever came forward, and the light Henley saw in his rear-view mirror may have been the Knowles car itself.

The family drove on to Ceduna, in South Australia, and went to the police station. Sergeant James Fennell told UPI the next day: "I inspected the car when it arrived at Ceduna. The car was covered in a thick coating of black ash and there was ash inside the car. There was slight damage to the roof of the car." He added that the family were "extremely distraught" and that "something happened out there"; Constable Bob Hagen said that after checking the car and seeing them, "we think there could be something in this."

Later inspections did not bear this out. Brunt, who reviewed the case in 1989, writes that the police and Australian UFO research groups inspected the car thoroughly on several occasions and that "none of these inspections showed anything unusual about the car": "There was no black ash inside or outside the car," only a black deposit on the metal rims of the two front wheels, consistent with brake-lining material; the rear right tire "had burst in a normal manner," as expected at high speed; and "the dents on the roof were insignificant, and there was no proof that they were not there before the event." The Australian Mineral Development Laboratory analyzed the outside ash and found clay and salt particles, consistent with a car that had crossed the Nullarbor, and an inspection commissioned by a TV station observed "no significant dust." Dr. Richard Haines of NASA Ames Research Center concluded that the dust inside the car differed from the dust outside, but later analyses by other labs found no anomalous material.

For the light itself there is a published explanation. Brunt, a former Regional Director of the South Australian Bureau of Meteorology, found that there was a marked temperature inversion (a layer of warmer air over cooler air, which bends light) along the whole southern coast of Western Australia that morning. He concluded that the family's first impression was right, a truck approaching from the east, and that what terrified them was the image of its headlights distorted by a superior mirage. Skeptoid (2020) endorsed that reading and added a "small group panic" and a tire blown out by excessive speed. It relies on a TV interview aired about 36 hours after the incident, in which Sean said he was doing about 200 km/h when the tire burst, just as they believed the object was landing on the roof; the Telstar's tires were rated for up to 180 km/h. The UPI story, by contrast, gives about 110 km/h.

Why it matters

The black ash the Ceduna police saw on the car that morning did not turn up in any of the later inspections, the roof damage came down to insignificant dents that may have been there before, and no analysis confirmed anything anomalous in the dust. The physical traces that made the story more than a scare on the highway did not hold up under examination.

The trucker Henley also saw the light, though it may have been the Knowles car itself, and there is a proposed cause backed by that morning's weather data: a temperature inversion able to distort the headlights of a distant truck into a bright shape that seemed to jump about over the road. That explanation accounts for the light, not for the "lifting" of the car, which rests only on the family's account, and within that account the sources disagree on who was driving, and Sean spoke of about 110 km/h according to UPI and about 200 on television.
